At the end of the test, the CO2 production of blank control groups were 38.09 mg/L.
Table 1. The percentage biodegradation of the test groups
Percentage of biodegradation (% ThCO2)a
Difference of replicateb
a Percentage of biodegradation (% ThCO2) = (cumulative CO2of test group (mg) -cumulative CO2of blank control group (mg)) / (added TOC (mg) × 3.67) ×100%
b Difference of replicate = Flask 1- Flash 2
Table 2. The percentage biodegradation of the reference and toxicity control group
Toxicity control group
a Percentage of biodegradation (% ThCO2) = (cumulative CO2of reference control group or toxicity control (mg) - cumulative CO2of toxicity control group (mg)) / (added TOC (mg) × 3.67) ×100%
This test using the procedures outlined in the SuperLab Study Plan for M62-151100099001EN which is based on the SOP for the OECD 301B (SOPE-503) and OECD 301B (OECD, 1992). The results of this OECD 301B test for Evercion SR61 show that all validity criteria were met. Evercion SR61 was not readily biodegradable under the test conditions and the percentage biodegradation of Evercion SR61 in sludge was less than 60 %.
Not readily biodegradable (OECD TG 301B).
The total amount of evolved CO2 in the blank control group was 38.09 mg/L. The difference between replicates of test group was less than 20%. At Day 14 during the study, the biodegradation of the reference control article was 69.33 % and the percent biodegradation in the toxicity control was 32.48 %. All test validity criteria were met. Evercion SR61 was not readily biodegradable under the test conditions and the percentage biodegradation of Evercion SR61 in sludge was less than 60 %.
